Niki Lauda has hit back at the critics who are slamming the revolutionary new face of formula one.

Ron Walker, the Australian grand prix chief who is a key Bernie Ecclestone ally, is leading the charge by threatening to sue the sport and switch to Indycar racing after hearing the sound of the new turbo V6 engines.

The two-time ALMS P1 championship-winning squad has elected to skip the races at Long Beach and Mazda Raceway Laguna Seca in order to focus on reliability and performance testing with its Oreca 03 Nissan P2 car.

Red Bull’s appeal against the exclusion of Daniel Ricciardo from the Australian GP is based on the team believing that the rules do not specify that fuel flow has to be measured by the FIA-mandated sensor.

Team boss Christian Horner says that the team’s own readings proved that Ricciardo did not exceed the 100kg/h limit, which is why the team ignored instructions from the FIA to adjust the flow.
